SPEAKER CONNECTION
When we designed the
E150P and E250P powered
subwoofers, our goal was
to offer the user the best pos-
sible performance combined
with the most flexible and
complete installation options.
Please look over the following
three examples to determine
which description best
matches your system and
follow the corresponding
hookup instructions.
To use the binding-post
speaker terminals with bare
wire, unscrew the collar until
the hole through the center
post is visible under the collar.
Insert the bare end of the wire
through the hole in the post,
then screw the collar back
down until the connection is
tight. The holes in the center
of the collars are intended for
banana-type connectors.
Speakers and electronics termi-
nals have corresponding positive
(+) and negative (–) terminals. It
is important to connect both
speakers identically:
positive (+) on the speaker
to positive (+) on the amplifier
and negative (–) on the speaker
to negative (–) on the amplifier.
Wiring “out of phase” results in
thin sound, weak bass and a
poor stereo image.
NOTE: The speaker-level con-
nection method described on
the next page is not a
preferred connection
and should only be
resorted to if your receiver/
processor does not have a
line-level or subwoofer output.
The customer is responsible for
proper connections, and any
damage to JBL or other equip-
ment due to improper connec-
tions will not be covered by
your JBL warranty. Consult with
your JBL dealer or an audio-
installation expert if you have
any questions about how to
connect your subwoofer using
the speaker-level inputs.

Analog Receiver/Processor – Speaker-Level Connections
Use this installation method
only with an analog receiver/
processor that does not have
digital processing or bass
management, and also does
not have a subwoofer output
or a volume-controlled preamp
(line-) level output:
Connect the speaker wires for
both your main left and right
speakers, and for the sub-
woofer, to the same speaker
terminals on your receiver or
amplifier. The wires may be
joined by twisting together the
bare ends of the two leads
that will be connected to each
terminal on the receiver/
amplifier, as shown in the
diagram. This procedure
should be done only four times
(involving a total of eight bare-
wire ends), and only for those
wire ends that are being con-
nected to the terminals on
your receiver/amplifier. It is
important that you avoid join-
ing any other wires. Do not
twist together
wire ends that
are being
inserted into
terminals on any
speaker or on the
subwoofer. Do not twist
together wire ends that will be
used for any speakers other
than the front left and right
speakers or the subwoofer.
Refer to the connection dia-
gram for guidance.
Twist together the (+) leads at
one end of the speaker wires
that you have designated for
the left front speaker and for
the left high-level inputs on
the subwoofer. Insert the
joined (twisted) wires into the
left front (+) terminal on your
receiver/amplifier. Connect the
free end of the (+) lead for the
left front speaker to the (+) ter-
minal on the back of the
speaker. Connect the free end
of the (+) lead for the left input
on the subwoofer to the left
binding-post terminal. Repeat
this process for the (–)
connections for the left front
speaker and left input on the
subwoofer, and then for the (+)
and (–) connections for the
right front speaker and right
high-level inputs on the sub-
woofer.
Connect your receiver or
amplifier’s center and sur-
round speaker terminals to the
corresponding terminals on
the back of your center and
surround speakers.

Digital Receiver/Processor – LFE Connection
Use this installation method
for Dolby Digital, DTS®or other
digital surround processors
that have bass-management
programming, or for analog
receivers/processors that
have a filtered subwoofer
output:
IMPORTANT: Make sure that
the LFE toggle switch on the
subwoofer is in the “LFE”
position. Use the line-level
input jacks for the Low-
Frequency Effects channel.
Connect these jacks to the LFE
output or subwoofer output on
your receiver or amplifier.
Note: If your receiver or ampli-
fier has only one subwoofer
output jack, you may connect
the subwoofer output on your
receiver/preamplifier to either
the left or right line-level input
on the subwoofer. It makes no
difference which jack you
choose.
Connect each speaker to
the corresponding speaker
terminals on your receiver or
amplifier.
Make sure that you have
configured your surround
sound processor for
“Subwoofer On” or
“LFE On.” The front,
center and surround
speakers should be
set to “Small” or “Large”
depending on their size and
frequency response. Consult
your receiver’s or processor’s
owner’s manual.

Analog Receiver/Processor – Line-Level Connections
Use this installation method
with an analog receiver/
processor that does not have
digital processing or bass
management, and that is
equipped with a full-range
subwoofer output or a volume-
controlled preamp (line-) level
output:
Use RCA-type interconnect
cables to connect the line-
level subwoofer outputs on
your receiver or amplifier to
the line-level inputs on the
subwoofer.
IMPORTANT: Make sure that
the LFE toggle switch on the
subwoofer is in the “Normal”
position. Do not use the
“LFE” position with Dolby*
Pro Logic*-only processors.
Note: If your receiver or
amplifier has only one sub-
woofer output jack, then you
may connect the subwoofer
output on your receiver/pre-
amplifier to either the left or
right line-level input on the
subwoofer. It makes no differ-
ence which jack you choose.
Connect each speaker to
the corresponding speaker
terminals on your
receiver or amplifier.
Make sure your receiver
or processor is config-
ured so
that the sub-
woofer is “On.”
Note for advanced
users: If your receiver/
processor has a built-in low-
pass crossover filter for the
subwoofer output, then the LFE
switch should be set to the
“LFE” position to bypass the
subwoofer’s internal
crossover.

OPERATION
When the unit is plugged in
and the power switch is on
and no signal is received, the
LED on the top of the unit will
turn red. When a signal is
present, the LED will turn
green.
Note: It will take several min-
utes for the LED to turn from
green to red after the input
signal to the subwoofer is
removed. Due to JBL’s unique
high-output, high-efficiency
amplifier design, power con-
sumption is minimal when the
subwoofer is not receiving a
signal. Of course, the sub-
woofer can be turned off,
whenever desired, if you do
not wish to leave it in auto
(standby) mode.
The subwoofer Level Control
adjusts the volume of the
subwoofer relative to the rest
of the system. Proper level
adjustment depends on sev-
eral variables such as room
size, subwoofer placement,
type of main speakers and
position. Adjust the subwoofer
level so that the volume of the
bass information is pleasing
to you.
Crossover Adjustments
The Crossover Frequency
Control determines the highest
frequency at which the sub-
woofer reproduces sounds. If
your main speakers can com-
fortably reproduce some low-
frequency sounds, set this
control to a lower frequency
setting, between 50Hz and
100Hz. This will concentrate
the subwoofer’s efforts on the
ultradeep bass sounds
required by today’s films and
music. If you are using smaller
bookshelf speakers that do not
extend to the lower bass fre-
quencies, set the low-pass
crossover control to a higher
setting, between 120Hz and
150Hz. This control is not used
when the LFE switch is in the
“LFE” position.

TROUBLESHOOTING
If you used the high-level
(speaker) inputs and there
is no sound from any of the
speakers:
• Check that the receiver/
amplifier is on and a source
is playing.
• Check that the powered
subwoofer is plugged into
an active electrical outlet
and is switched on.
• Check all wires and connec-
tions between the receiver/
amplifier and the speakers.
Make sure all wires are con-
nected. Make sure none of
the speaker wires are frayed,
cut or punctured, or touching
each other, except for the
wires for the front left and
right speakers, which may be
joined with the wires for the
subwoofer at the receiver/
amplifier end only, if you are
using the speaker-level
connections as described
on page 4.
• Review proper operation
of your receiver/amplifier.
If there is low (or no) bass
output:
• Make sure the connections
to the left and right “Speaker
Inputs” have the correct
polarity (+ and –).
• Make sure that the sub-
woofer is plugged into an
active electrical outlet and
switched on.
• Adjust the crossover point.
• Flip the Phase Control switch
to the opposite position.
• If you are using a Dolby
Digital/DTS receiver or
processor, make sure that the
subwoofer adjustments on
the receiver/processor are
set up correctly.
• Slowly turn the Level Control
clockwise until you begin to
hear the desired amount of
bass.
If you used the line-level
inputs and there is no sound
from the subwoofer:
• Check that the receiver/
amplifier is on and a source is
playing.
• Check that the powered
subwoofer is plugged into an
active electrical outlet and is
switched on.
• Check all wires and
connections between the
receiver/amplifier and the
subwoofer. Make sure all
wires are connected. Make
sure none of the wires are
frayed, cut or punctured, or
touching each other.
• Review proper operation of
your receiver/amplifier.
• Slowly turn the Level
Control clockwise until you
begin to hear the desired
amount of bass.
• Make sure that you have
configured your receiver/
processor so that the sub-
woofer/LFE output is on.
Phase Control
The Phase Control determines
whether the subwoofer’s pis-
ton-like action moves in and
out in phase with the main
speakers or opposite the
main speakers. There is no
correct or incorrect setting.
Proper phase adjustment
depends on several variables
such as subwoofer placement
and listener position. Adjust
the phase switch to maximize
bass output at the listening
position.
Remember, every system,
room and listener is different.
There are no right or wrong
settings; this switch offers the
added flexibility to adjust your
subwoofer for optimum per-
formance for your specific
listening conditions without
having to move your speakers.
If at some time in the future
you happen to rearrange your
listening room and move your
speakers, you should experi-
ment with the phase switch in
both positions, and leave it in
the position that maximizes
bass performance.

TECH TIPS
Troubleshooting tips and solutions to common service problems
For models: E150P,E250P and PB10,PB12 (Revision 2) * TIP# JBLTT2003-04 Rev1
Subject: Replacing MOSFETS Q18, Q22
In the event you need to replace MOSFET transistors Q18 or Q22 as part of a repair, it is important to use
ONLY the JBL part# FE106401110 or only the brands: International Rectifier, or Fairchild.
Replace both Q18 and Q22 MOSFET’s in the circuit, even if only one seems to be damaged.
Do NOT mix & match these components from different manufacturers, or batches. They should be
identical.
* Late version PB10 or PB12 subwoofers (Revision 2 in the service manual) can be identified by:
• Amplifier serial number starts with “HA”
• Output transistors in the open, on a large black heatsink
• Large plastic cup enclosing the rear of the amp assembly
• Main PCB, bottom, solder-side contains all SMD devices
